Fig. 7. Melanophore rescue by forced nac/mitfa expression in the neural crest of embryos from intercrossed cls/sox10^+/-,nac/mitfa^+/- double heterozygous parent fish. The plot shows what number of melanophores were rescued in what percentage of cls/sox10^-/- embryos (white squares) and embryos mutant for nac/mitfa but not cls/sox10 (black squares). The numbers of each class of embryo are shown in Table 4. A Mann-Whitney rank sum test shows no significant difference in the extent of rescue of these two classes of mutant (P=0.876).
